Description

Technical Field

[0001] This utility model belongs to the field of vehicle frame hoisting technology, and in particular relates to a vehicle frame hoisting tool. Background Technology

[0002] The vehicle body frame is the core load-bearing structure of an automobile. It supports the entire vehicle and ensures safety through a frame system made of high-strength materials. Its design directly affects vehicle performance and safety. The vehicle body frame lifting fixture is a special equipment used in automobile manufacturing for the safe transfer of the vehicle body frame. Its core design aims to achieve multi-specification adaptability, convenient operation, and safety and reliability. When lifting the vehicle body frame, the bottom of the frame cannot be stably limited, which makes it easy for the frame to shake during lifting, reducing the stability and safety of the frame during lifting. Therefore, a vehicle body frame lifting fixture is proposed.

[0003] For example, Chinese patent CN208234369U discloses a hoisting fixture for a bus roof frame, including a lower support beam for supporting and fixing the roof frame, two support blocks welded to the lower support beam, a support back plate with a round hole welded to each of the two support blocks, a handle welded to each of the two support back plates, and anti-slip pads installed at both ends of the lower support beam. The hoisting fixture is connected to the vehicle via a hoisting rope. In use, the two hoisting fixtures are placed in the front and rear sunroof holes of the roof frame and connected to the sunroof crossbeam of the roof frame.

[0004] The existing technical documents have the following problems:

[0005] Existing technical documents have some drawbacks in use, such as: the inability to stably limit the bottom of the frame during hoisting, leading to swaying and reducing stability and safety during hoisting; and the hoisting fixture is usually manufactured as a single piece, occupying a large volume and making transportation inconvenient. Therefore, we propose a new hoisting fixture for the vehicle body frame. Utility Model Content

[0006] The purpose of this utility model is to address the aforementioned technical problems by providing a vehicle frame hoisting fixture that achieves the effect of limiting and stabilizing the vehicle frame while facilitating the disassembly and assembly of the hoisting fixture.

[0007] In view of this, the present invention provides a vehicle frame hoisting fixture, including a frame, and further comprising: bushings equidistantly fitted on both sides of the frame, pins through which the surfaces of the bushings are installed, limit bolts through which the tops of the pins are installed, a lifting plate fixedly installed on the top of the frame, a frame column through which the bottom of the bushings is installed, a locking block fixedly installed on the opposite side of the frame column, a protective plate fixedly installed on the opposite side of the locking block, a positioning pin fixedly installed on the bottom of the protective plate, a trapezoidal groove fixedly provided at the bottom end inside the positioning pin, and retaining posts fixedly installed between the frame columns.

[0008] Based on the above structure, the trapezoidal groove is used to conveniently limit and clamp the bottom of different car body frames, preventing swaying during hoisting. The frame and frame column are disassembled by the cooperation of the pin and limit bolt, and then they are neatly arranged and reassembled when transported to the appropriate position.

[0009] Preferably, the lifting plate has through holes equidistantly arranged on one side, and the through holes are circular in shape, so as to facilitate the lifting of the lifting plate.

[0010] Preferably, a connecting sleeve is fixedly installed on the top of the protective plate. The connecting sleeve is made of alloy material and facilitates the connection between the column and the frame.

[0011] Preferably, an adjusting strip is installed through the bottom of the retaining column, and sliders are installed through the two sides inside the adjusting strip, so that the threaded rod can be connected to the adjusting strip.

[0012] Preferably, threaded rods are installed through both sides of the slider, and crossbars are sleeved on the surface of the threaded rods, so that the crossbars can be installed conveniently using the threaded rods.

[0013] Preferably, vertical bars are fixedly installed at both ends of the horizontal bar, and the cooperation between the horizontal and vertical bars facilitates the limiting function of the protective plate.

[0014] The beneficial effects of this utility model are:

[0015] 1. This vehicle body frame hoisting fixture uses a support column to movably connect a locking block, then uses the locking block to install a protective plate, then uses the bottom of the support column to install a positioning pin, and then uses the positioning pin to install a trapezoidal groove. Before hoisting the vehicle body frame, the locking block facilitates the movable installation of the protective plate on the support column. The protective plate then protects the sides of the vehicle body frame to prevent collisions and damage during hoisting. The trapezoidal groove then facilitates the limiting and clamping of different bottom parts of the vehicle body frame to prevent shaking during hoisting, thereby improving the stability and safety of hoisting the vehicle body frame.

[0016] 2. This type of vehicle frame hoisting fixture involves installing bushings on the frame, then installing pins and limit bolts on the bushings, and finally installing the lifting plate on the top of the frame. During transport, the frame and frame columns are disassembled in advance using the pins and limit bolts, and then the frame is neatly arranged. When transported to the appropriate location, it is then reassembled, which reduces the space occupied during transportation and improves the convenience of work transportation.
